I talked with my daughters ped and started making her milk after she weaned off breastmilk. I prefer doing that than buying anything else from the store because I can ensure she’s getting the proper nutrients without all the extra stuff. I also give her vitamin drops to put in her water so she can get additional nutrients.
Soy milk is usually the most nutritious highest protein most fortified etc and I personally like it the best but the nice thing about almond milk is that the unsweetened kind actually tastes ok whereas the unsweetened soy milk is pretty gross. There are loads of other kinds like coconut cashew oat etc but none really stand out for me either nutritionally or taste wise (though they’re all pretty good)
No milk at all! My Dr says we are thr only mammals who drink milk beyond infancy, and it's not necessary if he is getting a round diet.
My niece had tested out several that she had issues with digesting or just not liking. My sister in law uses kendamil, found at Target
